MACHINE FOR CUTTING MOLDINGS.

SPECIFICATION forming part of Letters Patent No. 286,423, dated October 9, 1883. Applicationfiled July 5, 1883. 1% model.

.To all whom it may concern/.-

Be it known that I, EDWARD L. GAYLORD, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Molding-Cutters; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel and useful improvements in machines for cutting picture and other moldings, and hasfor its object to provide such a machine as shall be cheap of construction, positive in all its moveand shall do the work quicker and in a better manner than has heretofore been done; and with these ends in view my invention consists in the details of construction and combi nation of elements, hereinafter fully and in de tail explained, and then specifically designated by the claims. A

In order that those skilled in the art to which my invention. appertains maymore fully understand its construction and operation, I will proceed to describe the same, referring by letters to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation of my improvement, showing the several parts in their 0perative position; Fig. 2, an enlarged front elevation of the upper portion of the same, the legs and foot-lever being broken away; Fig. 3, aplan view; Fig. 4, a detail sectional view,showing the connection between the shaft and the block; and Fig. 5, a detail plan view of the sliding plate.

bimilar letters denote like parts in the several figures.

A are the wardly-projecting flanges B of bed-plate C. Just under the bed-plate and moving in suitable guideways is a sliding plate, D, the function of which will be hereinafter explained. At the outer portion of this sliding plate is a lug, D, to which is pivotally attached the rod d, having a number of holes, (2, at its upper end for adjustment, as will be presently explained.

legs, to which are bolted down-' To the forward corners of thesliding plate D are bolted standards E, which form vertical guideways, in which move the tongues f f of the cutter-carrier F. This carrier is so constructed that its inner sides are inclined toward each other in rcctangularplancs, as seen at f Fig. 3. i

g are slots cut through the sides of the carrier F, through which pass bolts f into holes f of two cutting-knives, G, thereby securing said knives. The sides of the carrier to which the knives are secured being at right angles to each other, as hereinbefore set forth, the knives themselves are therefore in the same relation. The cutting-edges g are diagonal or oblique,

so that when they descend they will make a draw cut. Great power and certainty are insured by this arrangement of the knives, and

the most delicate moldings are out without split;

ting or marring in the least.

. H is a rectangular recess in the sliding plate D, the upper edges, 71, of whichform cuttingedges, so that when descend, the edges 9' of the knives G will'pass close to the said edges 71 cutting the molding smoothly. I 7

At the top of the carrier F is an upwardlyprojeotingdug, I, to which is pivoted the leyer J. Therear end of this lever is supported by apin, j, passing through rod d, and the forward end of said lever is supported by a pin, i passing through the rod K, the latter being pivoted by pin it passing through the actuat lug-lever L, which is secured to the shaft L.

M are blocks bolted between the flanges M tov insure firmness. To the lower end of these blocks are secured inwardly-proj ecting lugs or pivots m, which fit into recesses in the shaft L. (See Fig. 4.) Cast with or secured to said shaft L is a lever, N, projecting downwardly, and having an open head, N, through which passes a curved bar, 0, having formed on its inner end a foot-piece, O. This bar is adjusted in said head N by means of set'screw n, to accommodate the height of any operator.

It will be readily seen that a greater stroke can be gotten from a treadle of this construction than from those now in use on machines of this character, which is of the greatest imthe molding is'piac'ed on the sliding plate 1), and the'carrier caused to ICO portance where heavy work is to be done. I also add aweight, P, atthe rear end of said bar 0, to counterbalance the carrier F and keep it in an elevated position, as shown, and give momentum to the stroke, which does away with the use of springs, which latter occasion much loss of time and power.

At the rear corners of the sliding plate D of springs Q are attached, their forward ends being secured at q to the frame. The tendency of these springs is to throw the sliding plate D forward. plate is pivotally attached a connecting-rod, R, (see Fig. 3,) the forward end of which is pivoted at r to the hand-lever S, which is pivoted to the bed-plate O by means of screw 8.

Also, at the point r is secured the dog T. This 1 dog abuts against the ledge A, holding the sliding plate D against the tension of the springs Q. The ledge A is cast on the bedplate, so as to extend upwardly therefrom, and forms a bearing against which the molding is.

pressed while being cut.

Bolted to the bed-plate O in any suitable manner are graduated rests U, on which long moldings are supported and measured. These rests are fiush with the sliding plate, and the graduatinglines 1 2 3 4 5, 850., are oblique, as shown,

venience, brackets W, one of which is shown at Fig. 1, may be attached to the rear of the frame, to support work of anydescription.

The operation of my improvement is as follows: Having placed the molding to be cut on the sliding plate D, it is grasped tightly by thehandagainst the ledge A, when the treadle is operated by the foot, causing the carrier F, with knives G, to descend below the edges h of the sliding plate. This will cut the molding nearly in two 5 but there will still remain a small part uncut, owing to the fact that the knives in their descent did not come close to theledge A, against which the back of the molding abuts. Now, it isobvious that this is an advantage, as the knives passing through the wood at first make a rough out, which must be planed before a suitable finish is obtained. N 0W, without removing the molding, thelever S is grasped and pulled forward, which will move the sliding plate D backward against the tension of the springs Q, and as the carrier F is secured in standards E, bolted to said plate D, the angle f 2 of the knives will come in close proximity to the ledge A. By causing the carrier and knives to descend again, the small portion of the molding that remained uncut will be cut, and at the same time a shaving will be taken off from the ends that were cut at the first descent of the knives, leaving the ends of the molding perfectly smooth without necessitating the use of a planer.

The advantage in the sliding of the plate D, and the carrying of the carrier and knives therewith, is that when there isa very heavy Also, near the rear edge of said in order to coincide with the oblique or diagonalcutting of the molding. For 0011- ,molding to be cut it is operated on as follows: The dogT is turned back out of the way, as shown in dotted lines at Fig. 3, and by the action of the springs Q the sliding plate D will be thrown forward. In this position the carrier F and knives G will be removed some distance from the ledge A. The molding now being placed on the supports U and plate D, and the knives caused to descend, there will be but a small portion cut from the molding. The knives being allowed to ascend and the lever S pulled partially forward, thereby moving the carrier and knives backward and nearer the ledge A, said knives are again caused to descend, and will make a deeper cut, and so on the same operation continues until the molding has been entirely severed. By this means moldings of the largest size and of the hardest material may be readily out. In cutting moldings of unusual thickness, the normal position of thecarrier and knives may be raised by simply withdrawing the pins j and j, and raising the lever J, and then reini serting said pins in holes nearer the top of the rods cl K.

vOne of the most important advantages in my improvement is that the lever is stationary, and the molding therefore does not have to be moved at all, so that the latter can be held firmly against the ledge, and the plate it self shifted without any necessity onthe part of the operator for releasing his grasp on the molding, and also different cuts may be made as fast as the treadle can be worked; also, by

the swinging treadle I am enabled to get a greater vertical play of the knives with far greater power than in any machine of this class now in use; and by applying the power directly over the work, as clearly shown at Fig. 1, the greatest possible force is communicated to the knives.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is
